“Not all diagnostic trouble codes trigger a malfunction indicator light,” Toyota Collision Repair and Refinish Training assistant manager Eric Mendoza declares in the April film, available for free on the CRRT website. “… Therefore, if you rely solely on the dashboard to determine the scope of your repairs, then there could be concerns within your customer’s vehicle that you fail to address.”
Mendoza then demonstrates the Techstream Lite, Toyota’s term for a combination of any laptop that meets Toyota requirements, a MongoosePro MFC2 Interface cord from Drew Technologies and Toyota diagnostics software.
In the film, Mendoza hooks up the laptop with the cord and checks electronic control units for health codes through what appears to be a relatively straightforward procedure.
“Performing a health check is quick and easy and helps to ensure that you return your customer’s vehicle with all concerns addressed,” Mendoza concludes.
The video is a good resource and might help less tech-savvy auto body professionals feel less daunted by the idea of “scanning” a vehicle with an OEM equipment suite rather than an aftermarket technique.
Of course, there’s still the rest of the diagnostics process, in which a repairer determines how to fix everything indicated by those trouble codes. There’s likely also to be calibration of systems disrupted by the collision and subsequent repair process.
But not to worry — Toyota has participated in at least two other videos that might help a shop understand at least the calibration concept.
One produced by Auto Body Repair Network in 2015 and posted on the CRRT site features Mendoza and then-Lexus technicial and collision repair trainers manager Bill Zlaket. In it, the trainers discuss advanced driver assistance systems and why they need to be calibrated.
